Steganography techniques are useful to convey hidden information using various types of typically-transmitted multimedia data as cover file to conceal communication. When using JPEG as a cover file, normally message is hidden in the AC values of quantized DCT coefficients. However, concealment of message in quantization table is yet to be done. In this paper, a novel in-DQT technique for message hiding in JPEG’s quantization table using bytewise insertion is proposed. By using in-DQT technique on standard JPEG test images for cover files with up to 24 bytes of message, results show that steganography image with minimal acceptable image distortion. Thus, in-DQT technique provides alternative for embedding message in quantization table.
